There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

I and i

Science is an effective way for man to know the world.With individual objects as direct research objects,and general existing state of the objects as targets,with the help of scientific suppositions their verification and other methods to surpass gap among experience and superexperience targets,it obtains the knowledge of the objects.The study on general process and methods for scientific knowledge proves that science,which is based on experience and beyoud experience,is a way and method to verify experience.

Background:The purpose of this study is to determine the effect of an activity set developed according to the inquiry-based learning approach in the unit “Particulate Structure of Matter” on students’ critical thinking skills in science and technology courses.
The study was conducted with 90 sixth grade students attending four sixth grade classes of a secondary school.Material and methods:Within the framework of the study, in order to evaluate the effects of inquiry-based learning approach on the students’ critical thinking skills in science and technology courses, the guided activity set was developed by the researchers in line with the inquiry-based learning approach. In this study, pre-test and posttest control group experimental designs were used.Results:The findings of the study revealed that science and technology learning supported with the guided activities developed in line with the inquiry-based learning approach have significant effects on students’ critical thinking skills in science and technology courses.Conclusions:The critical thinking level of the experimental group students taught with the inquiry-based learning approach was found to be higher than that of the control group students taught with the traditional lecturing method.the critical thinking level of the experimental group students showed a positive increase in all the dimensions.

The Effect Of The Inquiry-Based Learning Approach On Student’s Critical Thinking Skills

Temperature dependent electrical and dielectric properties of Au/polyvinyl alcohol (Ni, Zn-doped)/n-Si Schottky diodes

Frequency and voltage effects on the dielectric properties and electrical conductivity of Al-TiW-Pd2Si/n-Si structures

The role of the interface insulator layer and interface states on the current-transport mechanism of Schottky diodes in wide temperature range

In this study, we have investigated the intersection behaviour of forward and reverse bias current–voltage (I–V) characteristics of Al/SiO2/p-Si Schottky diodes in the temperature range of 79–325 K. The crossing of the experimental semi-logarithmic ln(I)–V curves appears as an abnormality when seen with respect to the conventional behaviour of ideal Schottky diodes. Experimental results show that this crossing of ln(I)–V curves is an inherent property of even Schottky diodes. The ideality factor n was found to decrease, while the zero-bias Schottky barrier height (SBH) ΦB0 increases with increasing temperature. The conventional Richardson plot is found to be nonlinear in the temperature range measured. However, the ln(I0/T2) versus 1000/nT plot gives a straight line corresponding to activation energy 0.233 eV. It is shown that the values of series resistance Rs estimated from Cheung's method were strongly temperature dependent and abnormally increased with increasing temperature. In addition, the temperature dependence of energy distribution of interface states density Nss profiles was obtained from the forward bias I–V measurements by taking into account the bias dependence of the effective barrier height Φe and ideality factor n. All these behaviours indicate that the thermionic emission (TE) cannot be the main current transport mechanism, especially at low temperatures.
